* The film ''WesternAnimation/{{Nine}}'', the TropeNamer, involves 9 needing to go back to the room where he and the other stitchpunks were created in order to stop the Fabrication Machine. The talisman that allowed them to be created is most commonly termed "the Source" by the fanbase, as it did transfer the stitchpunks' souls into their bodies. Though in the movie, 6 was implied to actually be referring to the scientist who used the Source to create them...

--> "I thought I might go back to Godric’s Hollow… For me, it started there, all of it. I’ve just got a feeling I need to go there."
** In the next book, Hermione proposes an actual reason for going there. All is ultimately subverted when [[spoiler:nothing beneficial happens there. They don't find any of the unknown horcruxes, they don't find any information on the Deathly Hallows, Harry is nearly killed by Voldemort's snake, his wand is broken when he's rescued, and he later laments that he didn't even get a chance to kill the snake while he was at it (the snake being a horcrux).]]

The site also happens to be right next to the bamboo grove where the series's first scene took place.
